1- First of all download this file [Fonts file]:
http://download.yousendit.com/989F3A185AE3B386

2- Check your folder options to make sure that the option 'Show Hidden Files' is checked, to do that open any folder that you got there. From the main menu there go to Tools --> Folder Options and navigate to 'View' tab then to 'show files and folders' and check the 'show hidden files and folders' and we are done here.

3- After downloading this file and showing hidden files navigate on your computer to the following directory [Assuming that you are using Windows XP]:
C:\Documents and Settings\Your user name or account name\Local Settings\Application Data\Apple Computer\Safari

4- Copy the downloaded file to this directory, right click on it and choose 'Properties' then check the 'Read Only' option down there, you will find a similar font file there from before, rename it to anything that u want and we are done here.

5- Open your Safari browser now to see the difference :)

Hope this would be in a help.
Best Regards
